| 摘 要： | 试验了用柠檬酸＿Ａｌ（ＮＯ３）３溶液做溶剂分解磷灰石的预处理方法。结果表明，在微沸加热６ｍｉｎ条件下，质量浓度分别为３２ｇ／Ｌ和９０ｇ／Ｌ的柠檬酸＿Ａｌ（ＮＯ３）３混合溶剂可以有效地分解磷灰石，测定全磷的回收率＞９９％，与王水溶样结果相符，并用测定磷灰石标样中全磷进行验证，说明方法可靠。

| Abstract: | A chemical pretreatment method for the determination of total phosphorus in apatite with citric acid_aluminum nitrate as solvent is described in this paper. The results show that the mixed solvent of citric acid and aluminum nitrate with mass concentrations of 32 g/L and 90 g/L respectively can effectively decompose apatite. The recovery of phosphorus by this method is above 99%. The method is verified by the determination of total phosphorus in standard reference apatite samples. The results are in a good agreement with that obtained by aqua regia decomposition method. |
